While alcohol provides a significant number of calories—seven per gram, almost as much as fat—not all heavy drinkers gain weight, leading to a perplexing paradox often misunderstood by the public.

According to research, alcohol consumption can decrease muscle protein synthesis by at least 12 hours, with the greatest decrease occurring around four hours after intake. It is this disruption to the body's natural processes that directly answers the question: does alcohol affect amino acids? The impact is significant and widespread, touching everything from muscle repair to liver function.

Chronic alcohol consumption affects between 40% and 60% of individuals with chronic alcohol use disorder, leading to a condition known as alcoholic myopathy, which causes muscle weakness and atrophy. This complex issue stems from a combination of metabolic disruption, hormonal imbalances, and nutritional deficiencies that severely impact the body's ability to maintain muscle mass.

While the liver is the primary site of alcohol metabolism, some alcohol is distributed throughout the body's tissues. Muscle tissue, with its high water content, is capable of absorbing alcohol from the bloodstream, a factor that influences a person's blood alcohol concentration (BAC). This absorption process, however, does not remove alcohol from the system but rather dilutes it, with significant consequences for both fitness and general health.

Acute alcohol intoxication has been shown to decrease protein synthesis rates by as much as 37% following exercise. This demonstrates how alcohol, even in single high doses, can dramatically affect protein metabolism by hindering the body's ability to build and repair muscle tissue.

Chronic alcoholic myopathy affects up to half of chronic alcoholics, causing debilitating muscle weakness and wasting. A significant contributing factor is the severe nutritional deficiencies that result from prolonged alcohol misuse, especially of key B vitamins and vitamin D, which are involved in alcohol myopathy by disrupting crucial metabolic processes essential for muscle function and repair.

Chronic alcoholic myopathy affects up to 60% of long-term heavy drinkers, causing debilitating muscle weakness and wasting. While the condition has multiple causes, researchers have identified that specific nutritional deficits, most notably vitamin D deficiency, contribute significantly to the development and severity of alcohol myopathy.

Research indicates that even moderate alcohol consumption can decrease muscle protein synthesis by up to 37% following exercise. This fact is critical for anyone questioning if and how **does alcohol cause protein damage** to their body and overall health.

Despite alcohol's calorie content, studies show that many chronic alcoholics experience significant weight loss, becoming visibly frail. The answer to **why do alcoholics get skinny** lies in a combination of severe malnutrition, suppressed appetite, and toxic metabolic processes that damage the body.
